Exploration of the brain from its superior aspect

Close-up view of anterior part of lateral ventricle and interventricular foramen

Close-up view of central area of preceding stage of dissection seen from a more lateral angle. Details of the medial wall of the lateral ventricle and of the interventricular foramen are now evident. Note the small cavity of the septum pellucidum which has been cut open just beneath the corpus callosum. The ependymal lining of the ventricle is intact.
